PROBLEM TO BE SOLVED: To sense leakage of an organic electrolytic solution or a gas generated from an organic solvent likely to cause inflammation or explosion continuously, simply, and certainly. SOLUTION: In at least part of a vessel 1 or outside thereof, a leak sensor is provided to work with a laminate body 11 consisting of a sensor layer 11a and a pair of electrode layers 11b and 11c pinching the sensor layer 11a, wherein the sensor layer 11a contains highpolymers as a precursor of solid electrolyte and functions as an electrolyte when wetted and swollen with an organic solvent in an organic electrolytic solution to result in a change of its electroconductivity from before its being wetted and swollen. |
